About Us

Ronier developed a love for Heating and Air Conditioning while working with his brother throughout the nineties.  

By the early 2000's, Ronier launched Certified Comfort Heating & Cooling and has been serving the South Suburbs and Southside of Chicago ever since!

His favorite thing about being a service provider is helping others.  His favorite phrase is, "there's no charge for honesty!"

When not installing furnaces and tuning air conditioning units, he can be found as a proud family man cheering his son in basketball!
